T0 all lwhom t may concern p Be it know'. that I, JOSEPH KAUFMAN, acitizen of tlify United States, residing at New York, in the lcounty ofNew York and State of New York, have invented certain new and usefulImprovements in Razors; andl do hereby declare the following to be afull, cleanfandrexact description of the invention, such as will enableothers skilled in the art to which it appertainsto make and use thesame.

This invention relates to improvements in razors, and more particularlyto the type known as safety razors.

The object in view lis the improvement of a razor frame for increasingthe efficiency, oompactness, accessibility and finish, while embodyingthese features in a construction capable of production at a minimumexpense.

A further object in detail is the provision of especially effectivemeans for retaining a razor blade against dislocation during use.

With these and further objects in view, which will in part hereinafterbe stated, and 'in part become apparent, the invention com` prisescertain novel combinations, construc tions and arrangements of parts aswill be specified and claimed.

Iii the accompanying drawing,-Figure 1 is an edge view of a razorembodying the features of the invention, the hood being seen in itsclosed position. Fig. 2 is a top plan view thereof with the hood in itsopen position. Fig. 3 isa vertical, central section taken on the planeindicated by line 3--3 of Fig. 2. Fig. 4 is a similar section with thehood illustrated in its closed position.- Fig. 5 is a detail,perspective view of the rear springs detached and shown on a greatlyenlarged scale. Fig. 6 is a vertical section taken on the planeindicated by line 6-6 of Fig. 2.

Referring to the drawing by numerals, 1 indicates a handle of any welllmown or conventional type having its upper end threaded into the backplate 2 of a razor frame, the said plate curving upwardly from thehandle and being complete the frame in producing the blade supportingplate 3. The plate 8 terminates along its front edge in the usual safetyguard 4, at each end of which is arranged an upstanding lug or `detent 5adapted to serve as a stop against forward movement of a razor blade,indicated at 6, the blade bent forwardly to l being further retained inposition by guiding brackets 7 7, comprising tabsfor strips formed ofthe material of plate 3, at the ends thereof and intermediate the edgesof the blade, and bent back over the plate for overlapping the blade.The material of plate 3 is out awayat its rear edge, approximatelymidway between its ends, and the back 2 has its material cut away' atsubstantially the'same place for forming an opening 8 for accommodatinga plate spring 9 and co operating parts. The spring 9 is preferablybifurcated' at its lower portion and the arms of the bifurcation areriveted, as at 10, or otherwise fixed to the back 2, the spring 9extending upwardly from said arms into position for .swinging into andacross parts ,of the opening 8.

As indicated in dotted lines in Fig. 2, the back 2 is' of less widththan the length of plate 3, so that portions of the plate 3 outstandfrom .each edge of back 2, and a strip of the material of the razorframe projects rearwardly at each end of t-he rear edge of plate 3, eachof said strips being bent to form an eye 12. A hood 13 is disposed tocoperate with the razor frame and consists of a main or cover plate 14having pendent end flanges l5, 15, and a pendent rear fiange 16, thelatter preferably 'being comprised of a downwardly curved portion of thematerial of plate 14. The side flanges 15 may be similarly formed, orotherwise constructed as preferred. The plate 14 is disposed withrespect to its flan es to extend downwardly forwardly, preferably on acurved line, so as to have its forward edge lie flush with the loweredge of the end flanges. Thus the hood structure -13 is formed or shapedto present avsubstantially concavo-convex body. The rear Harige 16extends below the lower edge of the end flanges 15 and such extendedportion is notched longitudinally at each end, as indicated at 17,producing a Vlongitudinally extendin pintle 18 at each end of the hood,the sai pintles extending through and finding bearings in the eyes 12.Substantially midway of the length of the flange 16, the material of theflange is extended downwardly to produce a tab or tongue 19 whichextends forwardly a distance sufficient for engaging and coperating withthe upper, free end portion of spring 9 so as to cause the spring tomove forwardly during either opening or closing movement of the hood,

the end of the tongue 19 engaging the rear face of the spring 9 andriding past the same in an opening movement and into a firm` engagementtherewith in a closing 1novement,`the former position being indicated inFig. 3, and the latter in Fig. 4.

To insure maintenance of the blade 6 taut in its operative position, andalso t position the blade with its front edge in engagement with thedetents during assembling of the parts when the operator has not beencareful in positioning the blade, as for instance when the blade is lefta little in the rear of its operative position, a spring is disposed inthe rear portion of the hood 13 for engaging the 4rear edge or back ofthe blade. The said spring preferably in fact consists of a pair ofcooperating spring and 21, each having its rear end flattened to fitagainst the respective .portion of the wall of flange 16, and eachflattened portion being Yapertured, as at 22, for

' receiving a rivet or other securing means engaging the flange 16, thematerial of the spring throughout the said iiattened portion beingformed with a forwardly turned flange 23 bearing against and conformingin contour with the material of plate 14. The springs 20 and 21 are bentor otherwise directed fnrwardly on an incline, and are extended forhaving their free ends lapping and spaced forwardly from the flange 16.The said free ends preferably have a sliding engagement, one of thesprings being formed with a longitudinal slot 24, and the other with atongue 25, extending through the slot, the tongue terminating in anenlargementor head 26 beyond the slot for lockin the two springstogether but leaving tem free for relative longitudinal movement. It isobvious, of course, that as a matter'of assemblage, the slot 24 is ofsufficient length for permitting the edgewise passage of the head 26,the latter being of flat material the same as the material of V`thespring from which it is formed. After the interlocking of the springs bythe introduction of the head through the slot, the

springs are swung to a position of alinement, as seen in Fig. 5, and arethen ready to be secured by being riveted through apertures 26,.orotherwisefixed to the flange 16.

It will be observed that in operation the hood 13 is free to swing to anopen position outstanding rearwardly from the razor frame so as toafford maximum freedom of access, and to enable easy withdrawal andreplacement of the blade. It will also be observed that in applyingthe'blade it is only necessary to pass the forward edge of the samebeneath the retaining brackets 7 and forwardly into contact with thelugs 5, and then to snap the hood 13 closed. If by anychance the bladehas not been brought entirely to its operative position, the back of theblade will be engaged by the free end of the spring 20 and pressedforwardly to the nal position, the hood closing and being retainedclosed under thevspring pressure of spring 9 engaged by tongue 19. It isto be noted that the tongue 19 extends beyond the axis of the alinedpintles 18, and therefore whenever the tongue is below the plane of thataxis and in engagement with spring 9, the hood will be pressed towardthe closed position, and whenever the tongue is above the plane of thesaid axis and in engagement with the spring 9, the hood will be pressedrearwardly or toward the open position.

All reference to the disposition of parts, as upwardly or forwardly orthe like, throughout this specication contemplates a disposition of therazor with the handle arranged vertically, as when shaving, and theguard edge is considered the front edge. It is also obvious, of course,that the drawings are all on an enlarged scale, greater than the actualsize of the usual razor structure.

What I claim is 1. In a razor, the combination, with a frame and a hoodtherefor, of springs fixed to the hooolv at spaced points and havingfreeportions vlapping, and means connecting the free lapping portionsfor preventing lateral separation thereof, and allowing cop' erativespring action of the free portions of the springs.

2. In a razor, the combination with a frame having eyes outstandingrearwardly therefrom, of a hood comprising a top or cover plate, a rearedge flange extending downwardly from the cover plate, the end portionsof the flange being formed with pintles journaled in said eyes inposition for adapting the hood to swing pivotally from a positionsubstantially above the frame to a position outstanding lrearwardlytherefrom, and end flanges pendent from the cover plate and tapering tothe front edge of said plate, the plate being inclined for- Wardlysuflicientlv for causing its forward edge to lie substantially in thesame plane with the lower edges of the end flanges.

3. In a razor, the combination with a frame and a hood therefor, oflapping, plate.

springs carried by the hood, each spring having one end fixed to thehood and the other end free for spring movement, the free end of onespring lapping the free end of the other, and the springs being disposedfor having their free end portions exert pressure on a blade sustainedby the frame.

4. In a razor, the combination with a frame and a hood therefor, ofsprings ex- L tending longitudinally of the hood at the rear portionthereof, one end of one spring being fixed to the hood adjacent one endthereof, and one end of the other spring being fixed to the hoodadjacent the other end thereof, the said springs being extendedforwardly from the points of engagement with the hood and adapted forexerting forward pressure against a blade sustained by the frame.

5. In a razor, the combination With a frame and a hood therefor, ofsprings extending longitudinally of the hood, one of the springs havingone of its ends fixed to the hood adjacent one end thereof, and theother spring having one of its ends fixed to the hood adjacent the otherend thereof, said springs being extended forwardly from the points ofengagement with the hood and having their free ends lapping and disposedfor exerting pressure against a blade sustained by the frame.

G. In a razor, the Coinbinaiton with a frame and a hood therefor, ofplate springs fixed to the hood and having free end portions lapping andhaving a longitudinally shiftable engagement, the said springs beingdisposed for having their lapping portions exert pressure against ablade sustained by the frame.

formed with a longitudinal slot, and the Aother with an extensionprojecting through the slot, the springs being disposed for having theirfree end portlons exert pressure on a blade sustained by the frame.

8. In a razor, the combination with a frame and a hood therefor, ofsprings fixed to the hood and having lapping free end portions, oneofthe springs being formed with a slot and the other with an extensionprojecting through the slot and an enlargement carried by the projectionbeyond the slot, the springs being adapted to exert pressure on a bladesustained by the frame.

9. In a razor, the combination with a frame and a hood therefor having aflange, of a pair of springs, each of said springs having one endportion fixed to the fiange of the hood and having a fiange extendingfrom the fixed portion along the adjacent portion of the hood, thesprings being disposed to exert pressure against a blade sustained bythe frame.
